Thirty canola type promising genotypes of Brassica napus were evaluated for their stability at 10 different locations across Pakistan during 2009-10. Combined analysis of variance revealed highly significant genotype x environment (G x E) interaction .The mean seed yield (t ha -1) of these ten locations, ranged from 0.868 to 1.661 t ha-1. Seventeen genotypes produced more seed yield as compared to overall mean value i e. 1.353 t ha-1. The genotype Hyola 471 CL out yielded and produced 1.661t ha-1seed yield followed by genotype Hyola-432 and Hyola-76 with seed yield of 1.647 and 1.625 t ha-1, respectively. NIFA, Peshawer and NARC, Islamabad were identified as best locations with   an average seed yield of 2.562 and 2.545 t ha-1 followed by Dera Ismail Khan (2.459 t ha-1). The regression coefficient (bi) of genotypes ranged from 0.80 to 1.32.  Genotype Shiralee was the most stable and well adaptive genotype because it showed above average performance (1.454 t ha-1), bi- value nearer to unity (bi = 1.02) and less value of deviation from regression (0.07), therefore, this genotype has wider adaptability and recommended for cultivation on diverse environments across the country. The genotype Hyola-471CL, Hyola-76, OMEGA-II and SPS-N20 were suitable for favorable environments and the genotypes RBN-03255, RBN-03046, OMEGA-III, and Hyola-433 were suitable for unfavorable environments.

Keywords: Brassica napus, stability analysis, genotype x environment interaction, Pakistan.
